Abstract (en)

[origin: EP0661332A2] A silicon-containing polymer comprising, in its backbone, at least 30 % by weight of at least one structural unit selected from the group consisting of -Si(R<1>)(R<2>)-C6H4-p-Si(R<1>)(R<2>)-CH2CH2-, -Si(R<1>)(R<2>)-CH2CH2-SiMe2-C6H4-pSiMe2CH2CH2- and -Si(R<1>)(R<2>)-C6H4-m-Si(R<1>)(R<2>)-CH2CH2- in which R<1>, R<2> and R represent a C1-C20 organic group or a halogen atom, provided that R<1> and R<2> are different in the formulas (1) and (2) or are the same or different in the formula (3) and having, as a terminal group, a vinylsilyl group of the formula: CH2=CHR'-Si(R)2- in which R is a C1-C20 organic group or a halogen atom, and R' is a hydrogen atom, a methyl group, a phenyl group or a trimethylsiloxy group, which polymer provides a cured material with excellent heat resistance.dried
